摘　　要：文章论述三连杆整体桥悬架的基本结构及其在短轴距轮距新能源车中的优势,对比传动油车和新能源车三连杆整体桥悬架减振器布置形式的差异,分析某新能源车减振器在满载侧倾和单侧深坑工况时衬套偏摆角过大的原因。通过Isight软件集成Adams/Car对减振器衬套偏摆角进行灵敏度分析,根据分析结果找出对减振器衬套偏摆角最敏感的悬架硬点,结合整车性能、空间布置和结构设计等找出衬套偏摆角的优化方法,消除减振器漏油风险,为新能源车三连杆整体桥后悬架的设计开发提供参考。This paper discusses the basic structure of three-link integral bridge suspension and its advantages in short wheelbase new energy vehicle, compares the difference of shock absorber layout form of three-link integral bridge suspension of transmission oil vehicle and new energy vehicle, analyzes the cause of the bushing yaw angle is too large when the shock absorber of a new energy vehicle is loaded with roll and single side deep pit. In this paper, Adams/Car is integrated with Isight software to carry out sensitivity analysis on the yaw angle of shock absorber bushing. According to the analysis results, the suspension hard point which is the most sensitive to the yaw angle of shock absorber bushing is found, and the optimization method of the yaw angle of shock absorber bushing is found based on the vehicle performance, spatial layout and structural design, so as to eliminate the risk of shock absorber oil leakage.It provides reference for the design and development of new energy vehicle three-link integral bridge rear suspension.
